Necessary and suficient conditions are established, which allow a seismic trace, recorded at the surface of a stratified, perfectly elastic medium, to be considered as resulting from all the direct and multiple reflections of a plane, compressional wave propagating normally to the strata.

The minimum modifications to be carried out on an observed trace in order that the above conditions be satisfied, is discussed.

When this condition is satisfied, it is possible the variation of the velocity of the elastic waves in the medium to deduce, from the seismic trace.

The complete process is shown in detail by a practical example. Some other results are given.
